Abstract

In this paper, we propose an architecture synthesis methodology to realize cascaded infinite impulse response (IIR) filter in table look up (TLU) field programmable gate arrays (FPGA). The synthesis procedure involves a systematic transformation of the dependance graph (DG) corresponding to the cascaded IIR filler to a pipelined fixed full size array (PFFSA). We offer an implementation of a cascaded 8th order IIR filters on Xilinx XC3090 FPGA devices.
